PIPE- VISE FOR BENCH-VISES.

SPECIFICATION forming part of Letters Patent No. 226,410, dated April 13, 1880. Application filed January 19, 1880.

To all whom it may concern Be it known that I, FRANCIS I. MAULE, of Philadelphia, Pennsylvania, have invented a new and useful Pipe-Vise for Bench-Vises, of which the following is a specification.

This invention relates to that class of Vises known as pipe-Vises, for securely holding wrought iron pipes while being cut and threaded.

The object of myinven tion is to construct a vise that will hold pipe and bind it securely while the workman is manipulating it.

It consists of a box or frame, to the end of whiclrframe a pair of V-shaped jaws are rigidly secured. Between these jaws projects a loop or hook, which is fitted to slide within the above-mentioned frame, and by means of a screw working in the opposite end of the hook the hook is drawn toward the fixed jaws This pipe-vise is constructed to be easily clamped in the ordinary bench-vise.

In the drawings, Figure 1 is a section through the ease or box, showing the internal construction of the working parts. Fig. 2 is an edge view, showing flange for bolting to an gle-plate on bench. Fig. 3 is a plan of the top of the vise. Fig. 4 is a side elevation, showing the operation of the jaws on a section of pipe. Fig. 5 shows another form of movable jaw.

The outer box or case, A, is made in one or more pieces of cast or wrought iron, having the stationary gripingjaws D firmly riveted to it.

B is a movable jaw projecting beyond the end of the box A. It is connected with and forms a part of the sliding cross-bar N within the box. This cross-bar is threaded to fit the screw 0, which has a collar, 0 and a crossbar lever, 0. Into the top of the movable jaw steel griping-jaws E are fitted.

The upper and lower jaws, E D, are of steel, serrated, to hold the pipe more securely.

K-is a removable lid, whichis bolted to the box after thejaw B is in place. Thejaw B is made somewhat in the shape of a hook, open at one side, thus permitting the pipe to be placed in position from the side of the vise.

ln my invent-ion the pipe can be griped at any desired point. The interior sides of the box guide the movable jaw B, as it advances or recedes, by the turning of the screw 0.

In Fig. 5 I show a modified form of the movable jaw B t'or extra heavy work. In Figs. 2 and 3 is shown a rib, a, cast or bolted to the under side of the casing A, by means of which the vise can be held in thejaws of an ordinary bench-vise; or it may be attached to suitable an gle-plates, and thus held firmly to the bench while being used.

I claim- 1. The combination of the hollow box A, suitable for clamping in vise-jaws, the fixed jaws D at one end of the box, the slidingjaw B, the threaded cross-bar N, sliding within the box, the screw 0, and lever 0, operating substantially as described.

2. The combination of the box or frame A, the fixed jaws D at one end of the box, a sliding hooked jaw, B, open at one side, and the threaded sliding cross-bar N, operated by the screw 0, as herein described.

FRANCIS I. MAULE.
